After pondering for a moment, Zhou Xing suddenly reached out and touched the holographic screen, called up the holographic design software, and started building a network model.
The virtual model in the holographic screen is constantly changing in Zhou Xing's hands, presenting a complex and precise model diagram, as if the bright starry sky is linked into a network.
In the laboratory command center, Zhou Xing was busy with concentration, and the virtual model structure became more and more complex.
As time passed bit by bit, scientists gradually discovered this situation, and they gathered around.
"What kind of model is this? The structure is so complicated!"
"The model looks like a human brain neural network, but the material is very strange, and the medium structure does not look like biological cells."
"The medium point of the model looks a bit like a photon cluster. What kind of model is this?"
"The structure is too complex, with so many link points, and the energy band effect produced by frequency light waves is used. Can this model finally be established?"
“…”
The scientists surrounding Zhou Xing began to discuss in low voices. They were confused by Zhou Xing's design model, and most of them could not understand the purpose of the model he designed.
However, they surrounded Zhou Xing and were still unwilling to leave.
After so many years, Zhou Xing is now more like a conductor in the scientific field. From the experimental command center, he remotely directs scientists around the world to launch an "attack" on a breakthrough point in a certain scientific field. He rarely takes action himself. A "battle".
At this time, Zhou Xing built a project model on his own, which immediately aroused strong curiosity among scientists.
In the blink of an eye, two hours passed.
Zhou Xing stopped moving his hands frequently, and a smile appeared on his tired face.
"Xiaozhi deduces this designable plan and confirms the results." Zhou Xing gave an order to Zhou Xiaozhi.
"Okay, boss!" Zhou Xiaozhi readily agreed. Immediately, the holographic screen changed, and complex deductions and calculations were started on Zhou Xing's design plan.
The dots of silver light dots in the holographic screen were beating crazily, and the veins of silver light were flickering, making it dazzling to see.
"Mr. Zhou, what kind of model is this? Neuron network?" Professor Lin Hai looked at Zhou Xing and asked uncertainly.
Zhou Xing turned to look at Professor Lin Hai, smiled and nodded: "Yes, it's a neuron network."
Hearing this, Professor Lin Hai perked up and asked excitedly: "Mr. Zhou, are you designing a biological computer?"
Neuron networks are standard in biological computers.
Biological computers are also called bionic computers. Their main raw materials are protein molecules produced by bioengineering technology. They are used as biochips to replace semiconductor silicon wafers and use organic compounds to store data.
The information of the biological computer is propagated in the form of waves. When the waves propagate along the protein molecular chain, it will cause changes in the structural order of single bonds and double bonds in the protein molecular chain. It has strong anti-electromagnetic interference capabilities and can completely eliminate circuits. The energy consumption is one billionth that of ordinary computers, and it has huge storage capacity. Biological computers have many characteristics of living organisms. They can exert their own regulatory functions, automatically repair faults that occur on the chip, and can imitate How the human brain works…
Today, when photonic computers are becoming popular, biological computers still occupy a certain position due to their many advantages.
As soon as Professor Lin Hai finished speaking, Professor Verus immediately retorted: "No, it's not a biological computer. This model uses non-biological materials. A biological computer cannot be established."
Hearing this, the professors all fell into silence as they looked at the model on the holographic screen.
A biological computer that simulates a neuron network must be built to completely simulate the operation of a neuron network, which is a complex biological activity. The small amount of materials used in the model is absolutely unable to simulate this system.
Neuronal network activity is an extremely complex process.
Neurons, also known as nerve cells, are the basic units that constitute the structure and function of the nervous system. They have long synapses (axons). They are composed of cell bodies and cell processes. The long axons are covered with a sheath. Nerve fibers, the small branches at the end are called nerve endings. There are patches of extranuclear chromatin in the neuron cytoplasm. There are also many neuron fibers. The slender parts of the system protrusions extending from the cell body can be divided into dendrites. and axons, each neuron can have one or more dendrites that can receive stimulation and transmit excitement into the cell body.
There is a sensitive and excitable membrane on the surface of nerve cells. There are various receptors and ion channels on the membrane. The receptors on the membrane can combine with the corresponding chemical neurotransmitters. When the receptor binds to acetylcholine transmitter or γ-aminobutyric acid transmitter, the ion permeability of the membrane and the potential difference between the inside and outside of the membrane change.
Neurofilaments, microtubules, and microfilaments, these three types of fibers constitute the cytoskeleton of neurons and participate in material transport... The activity of the entire neuron network is an extremely complex process that determines the interaction between the functions of various organs and systems of the entire organism. connect.
Although the model in front of you is very complex, it is limited by the materials used and is absolutely unable to simulate the activities of a biological neuron network system. In particular, this neuron network model is similar to the human brain.
The activities of the human brain include: neural stem cells, excitatory neurons, inhibitory neurons, astrocytes, oligodendrocytes, microglia, neural networks... At the same time, there are also various somatic cell activities, Protein sequence libraries are linked together, which is an extremely complex three-dimensional structure system.
The complexity of the human brain far exceeds human cognitive abilities. The human brain acquires, processes, processes and advanced cognitive mechanisms of complex information, acquires and processes neural information, and various operating rules... Even in this interstellar age, humans are still Not being able to understand your own brain.
"Mr. Zhou, what materials are used for the neurons in the model? Photon clouds?" Professor Lin Hai withdrew his speculation about the biological computer, looked at Zhou Xing and asked curiously.
"It's a photonic crystal." Zhou Xing replied with a smile.
Hearing this, all the scientists showed surprise.
Photonic crystal refers to an artificial periodic dielectric structure with photonic band gap characteristics, sometimes also called PBG photonic crystal structure. Photonic band gap means that waves in a certain frequency range cannot propagate in this periodic structure, that is, the structure itself There is a "forbidden band".
Photonic crystal is an artificial microstructure composed of periodic arrangements of media with different refractive indexes. Photonic crystal is a photonic bandgap material. From the perspective of material structure, photonic crystal is a type of artificial microstructure with periodic dielectric structure on the optical scale. Designed and manufactured crystals.
From the perspective of material structure, photonic crystals are a type of artificially designed and manufactured crystals with periodic dielectric structures on an optical scale. Similar to the modulation of electronic wave functions by semiconductor lattices, photonic bandgap materials can modulate the corresponding When the electromagnetic wave propagates in the photonic band gap material, it is modulated due to the presence of Bragg scattering, and the electromagnetic wave energy forms an energy band structure.
Simply put, photonic crystals have the function of wavelength selection, which can selectively allow light of a certain wavelength band to pass through, or prevent light of other wavelengths from passing through. According to the characteristics of this material, yes, this material can produce more diverse Variety.
However, can photonic crystal materials meet the needs of neuron network models? This model cannot be established!
For a moment, the scientists all had puzzled looks on their faces.
"Mr. Zhou, do you plan to use this material to simulate neuron networks?" Professor Verus looked at Zhou Xing and asked.
"Isn't this unnecessary! If you want to build a neuron network, you must use protein molecular materials!" Professor Malos frowned and asked strangely.
"Yes! How can a neuron network not use biological materials?" Professor Lin Hai raised his eyes and said in confusion.
All the professors looked at Zhou Xing with doubts in their eyes.
Neuron networks are the standard for biological computers. Likewise, protein molecule materials are the standard for refining biochips. There is no other material that can compare with them.
Zhou Xing looked at everyone and sighed: "Let's watch Xiaozhi's deduction first! If this design model cannot be successful, it will be useless no matter how much I explain."
"How is that possible? Mr. Zhou, there must be a reason for you to do this!"
"This is the model you designed, it will definitely succeed!"
"Yeah! I think so too."
“…”
After seeing this design model, the professors all made their own judgments, but in front of Zhou Xing, a genius scientist who was good at creating miracles, everything became difficult to say.
Zhou Xing ignored everyone's flattery, his eyes fell on the holographic screen, watching Zhou Xiaozhi's deduction process.
The model of silver light flashes, and the flashing silver dots are densely packed, like a starry sky, undergoing complex calculation changes. This process is like trillions of DNA molecules undergoing chemical reactions under the action of some biological enzymes, and simultaneously producing Tens of trillions of calculations.
…
Ten minutes passed, and the changes on the holographic screen finally stopped.
"Boss, the deduction has been passed, and the implementation success rate is 100%. However, the neuron computing network built using this kind of material cannot exceed the computing power of ten trillion times per second, and cannot replace Xiaozhi's current computing system! "Zhou Xiaozhi replied to Zhou Xing with a slightly disappointed voice.
Hearing this, Zhou Xing showed an expected smile and felt very satisfied.
Hearing this, the scientists looked at each other and suddenly understood the purpose of Zhou Xing's design of this model.
"Mr. Zhou, you plan to update Xiaozhi's 'hardware'. In this way, don't you have to change Xiaozhi's operating mode?" Professor Lin Hai looked at Zhou Xing and asked in surprise.
"Xiao Zhi needs to increase his computing power to support our development, so we can't stay the same!" Zhou Xing explained with a wry smile.
Hearing this, all the professors' eyes lit up. Zhou Xiaozhi is the core of the development of human civilization. His computing power directly affects the development speed of human civilization. The sooner this is done, the better.
"Is it because biological materials cannot match Xiaozhi's 'core components'? The idea of neuron networks is correct, but photonic crystals are not a bad choice!" Professor Li Yan thought for a moment and objected.
"Yes! The photonic crystal material is too simple to simulate the complex changes of the neuronal network. Xiaozhi's deduction results have confirmed this problem." Professor Varus looked at the holographic screen and said.
"What about three-dimensional photonic crystal materials! Coupled with nanowires and integrated into organic protein materials, it should be possible to build a qualified 'neuron cell'." Professor Lin Hai looked at Zhou Xing and suggested.
"No, organic protein ingredients cannot be integrated into the operating environment of the 'hardware system'." Zhou Xing looked at Professor Lin Hai and retorted.
Hearing this, the professors frowned and realized that solving this problem was very difficult.
The instrument that reproduced Zhou Xiaozhi's core data is a very precise and complex device. It must operate at extreme low temperatures under extreme vacuum. The temperature of the operating environment of the external "components" must not be that high. In this state , all organic organisms will lose their activity, so the materials for computational models will be limited to a very narrow range.
"Mr. Zhou, photonic crystals cannot meet the requirements, why not try metamaterials?" Professor Lin Hai looked at Zhou Xing and suggested.
"Yes, for example, multi-dimensional supercrystals have different properties. The conduction band and valence band are the same and vary in different layers. There are also changes between zero band gap and negative band gap... Materials like this should be able to meet the changes of neurons. Request." Professor Varus looked at Zhou Xing and suggested.
Hearing this, Zhou Xing showed a thoughtful look and then shook his head.
Metamaterials, also known as metamaterials, micro-nano structures, superdielectrics, anisotropic media, artificial electromagnetic media... In a broad sense, they also include photonic crystals, and more often they construct artificial units and artificial atoms to achieve photothermal and acoustic forces. the use of.
For example, a superlattice is composed of two semiconductor materials with different band gaps. Each quantum well will form a new selection rule that affects the movement of charges in this structure. They alternate along a certain period. Specific growth direction deposition... The structure is sometimes called a coupled multiple quantum well. Such complex changes are still difficult to meet the needs of simulating photon neurons.
Seeing Zhou Xing shaking his head and looking lost in thought, Professor Lin Hai sighed in frustration: "Alas! If there was a material between biology and metal, we wouldn't have to go through such trouble!"
Hearing this, the professors were silent for a while. With the development of scientific and technological civilization of human civilization, they have clearly understood the universe and are capable of developing various advanced technologies and sophisticated equipment and instruments. However, many designs can only be recorded in data. Curry, put them on the shelf.
Because of the material problem, it has become the biggest problem limiting the development of human civilization.
For example, if suitable materials are used for the neuron model designed by Zhou Xing, this neuron computing model can produce an astronomical amount of computing power, which is expected to be hundreds of thousands of times that of Zhou Xiaozhi's current computing power.
For a moment, the entire experimental command center fell into silence, and everyone was thinking about a better plan.
